JOSEPH MACKERT, OF SEATTLE, WASHINGTON.

UMBRELLA.

To all whom it may concern Be it known that I, JOSEPH MACKERT, citizenof the United States, residing at Seattle, in the county of King andState of WVashington, have invented a certain new and useful Improvementin Umbrellas, of which the following is a specification. My inventionrelates to improvements in umbrellas and its object is to provide acheap, strong, and simply constructed umi brella that may be turnedinside out without sustaining injury.

Numerous umbrellas of the ordinary type are broken by being caught bythe wind and turned inside out and it is my purpose to eliminate thistrouble by providing an umbrella that has its ribs so hinged that theumbrella may be turned inside out and again brought back to its normalposition Without injuring any of its parts. I attain this object bydevices illustrated in the accompanying drawings, wherein Figure 1 is avertical sectional view of an umbrella embodying my invention in itsnormal raised position, Fig. 2 is a vertical sectional view of a similarumbrella as it appears when it is turned inside out, Fig. 3 is anenlarged view of the rib joint embodied in my invention when the rib isin its extended position, Fig. 4. is an enlarged r b joint as it appearswhen the umbrella is turned inside out and Fig. 5 is an enlargedsectional view on the line 00, x of Fig. 3.

Like reference numerals indicate like parts throughout the drawings.

Referring to the drawings, 6 is a fixed sleeve of the usual typepositioned near the upper end of an umbrella rod 7 and having radiatingarms or lugs between which are pivotally mounted the upper ends of aplurality of radiating ribs, each rib consists of two parts, an upperrib 8, 8 and a lower rib 9, 9 which are pivotally connected by two link10 and 11 respectively. The lower end of the rib 8 is provided with aguide collar 12 adapted to slide over the rib 9 and normally adapted toseat within the notch 13 on the bottom side of the rib 9. The lower endof the rib 8 is also provided with a spring 14 which projects beyond theend of said rib and is adapted to bear on the top side of the rib 9 andnormally to seat within the notch 15. The sleeve 16 having a pluralityof radiating arms or lugs 23 between which are pivotally mounted thelower ends of a plurality of brace ribs 17 is slidably Specification ofLetters Patent.

mounted on the umbrella rod 7 in the usual manner, the upper ends of thebrace ribs 17 being pivotally connected to the lower main rib 9. Thelink 10 has its one end pivotally attached to a stud 18 on the upper rib8 and its other end pivotally attached to one end of the link 11, theother end of the link 11 being pivotally attached to the upper end ofthe lower rib 9. A pin 19 which projects from either side of the link 10is adapted to engage an offset 20 provided on its upper end of the link11 and thus prevent the links 10 and 11 from folding backward on eachother. The upper end of the rib 9 terminates in a hook-shaped member 21which is normally adapted to have its end positioned be tween the twosides of the link 10 and to have its point rest upon the bottom of saidlink 10, as illustrated in Fig. 5, thus serving as a stop and guide andgreatly strengthening the pivotal structure.

My umbrella when in the normal raised or lowered position conformssubstantially to the ordinary type of umbrella and opens and closes inthe usual manner, but when it is caught by the wind and turned insideout the pivoted links 10 and 11 are thrown outward and backward asillustrated in Fig. 2, thus allowing the ribs to be turned backwardtoward the umbrella tip without injuring any of their parts. WVhen theumbrella is turned inside out it may be lowered by lowering the sleeve16 and each rib may be restored to its normal extended position byexerting a slight pull on its lower end. l/Vhen in its normal positionthe spring 1 1 rests within the notch 15 and the collar 12 rests withinthe notch 13 thus preventing the umbrella from turning inside out or therib joints from becoming operative when the umbrella is being raised orlowered in common use, but when a force sufficiently strong to turn theumbrella inside out is exerted the spring 1 1 and the collar 12 aremoved from the notches 15 and 13 respectively and allow the rib jointsto become operative thus preventing the ribs from being broken.

Obviously minor changes in the details of construction of my umbrellamay be made within the scope of the appended claims without departingfrom the spirit of my invention or sacrificing any of its advantages.

What I claim is:

1. In an umbrella of the class described, the combination with anumbrella stick, of a plurality of radiating ribs each of which comprisesan inner and an outer member each inner member of said ribs having oneend articulated with said umbrella stick, a double link joint pivotallyconnecting the other end of said inner member and the inner end of saidouter member, detent means provided on the outer end of said innermember to allow said outer member to swing in one direction only, and aspring associated with the inner endof said outer member normally toprevent said outer member from swinging in said direction.

2. In an umbrella of the class described, the combination with aplurality of ribs each of which comprises two members, of a double jointarticulating one member with its mate and permitting one of such membersto swing in one direction'only with respect to the other of saidmembers, whereby one In witness whereof, I hereunto subscribe my namethis twentyefourth day of'March A. D. 1913.
